    Giotto Premium Plus: Pressure gauge sticks on .15 bar when cold

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Not sure when this started happening but I recently noticed the boiler pressure gauge no longer returns to zero when cold. It bottoms out around .15 bar. It otherwise appears to work as expected, though I have no idea whether it's reflecting the actual boiler pressure.

    Any ideas what might be causing this?

    Thanks

    It's probably a small rock of limescale blocking the capillary tube to the gauge. Can be a sign that descale/service is required

    Makes sense. Shouldn't need descaling though, did that recently. Perhaps I dislodge a chunk of scale in that process.
